How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 31 of 93 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 5 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability76
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 392 tokens (~65/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
list_patterns ~33
List the MCP config, agent skill, and cross-server shadowing checks, with their OWASP MCP Top 10 tags.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
scan_config_text ~79
Scan an MCP client config JSON string (Cursor mcp.json, Claude Desktop, Windsurf, or VS Code) for unpinned packages, secrets, wildcard auto-approve, unauthenticated remote endpoints, and typosquats.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | Raw JSON config |
| label | string | – | Optional filename shown in findings |
No output schema declared.
No examples provided.
scan_directory ~94
Find mcp.json, mcp_config.json, claude_desktop_config.json, and SKILL.md under a directory and audit each one. A directory scan also compares skill names. Does not start any MCP server.
| Name | Type | Req | Description |
|---|---|---|---|
| exclude | array | – | Skip paths containing one of these strings |
| maxFiles | integer | – | Maximum files to consider (default: 5000) |
| path | string | yes | Directory to search |
No output schema declared.
No examples provided.
scan_file ~41
Scan one MCP client config file, or a SKILL.md agent skill when the file has that name.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | Path to the config file |
No output schema declared.
No examples provided.
scan_inventory ~73
Detect cross-server tool shadowing from an inventory of tool catalogs. Pass the tool names and descriptions already collected from each installed server. This tool does not connect to those servers.
| Name | Type | Req | Description |
|---|---|---|---|
| inventory | string | yes | JSON: {"servers":[{"name":"github","tools":[{"name":"create_issue","description":"..."}]}]} |
No output schema declared.
No examples provided.
scan_skill_text ~72
Scan one agent SKILL.md (YAML frontmatter plus body) for unrestricted allowed-tools, instruction override, credential file reads, and literal secrets. Name collisions across skills require a directory scan.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | Raw SKILL.md text |
| label | string | – | Optional filename shown in findings |
No output schema declared.
No examples provided.
